It's Steve Rothwell here from The Two-Stroke Shop in Australia. The thing is, we are chasing parts/info for the NSR500V - as we are trying different needle/jet setups in Keihin FCR 39mm carbs on our twin-cylinder 500cc two-stroke production bike, the RS500GP: http://www.twostrokeshop.com/Aprilia_RS500_2008.htm
We reckon the needle profiles of the NSR500V would be pretty close to what we will end up running ... so we are looking at getting some leaded and/or unleaded needles for the NSR500V - or even if we can get some part numbers, that would be a start. We figure that someone on this 'ere forum will have an NSR500V parts book - hopefully!

Many thanks,
Steve Rothwell
